.applic-ation' filed September 7, 1922. Serial No. tlmt.

headlights, and is particularly intended to provide an automobile headlight of the antiglare type, whereby there shall be no displaced rays to be wasted. but .all rays of light are utilized. y

The invention comprises a casing of peculiar shape, with a source of light therein i comprising an incandescent electric lamp bulb preferably of the battery type and lo cated in a reflector bowl in the focus thereof and directed toward an inclined mirror also y containedwithin the casing in such position vassociated therewith coactin that the rays of light are directed toward one end of the bowl of the 'casing where there is a light emitting opening of circum scribed area, the plane reflector and the bowl or focusing reiiector coacting to condense and reflect the rays of light through the circumscribed opening to a point on the road in front of the automobile distant from the headlight, the reiiector bowl and the mirror the, rays of light and direct t em in a mann ner to prevent any glare reaching the eyes of an observer in front of the automobile, the reflected raysv of light being directed in a low path below the eyes of the observer, While at the same time the illuminating quality of the ra s of light being ample to light up 'the roa way so as to amply show any obstructions that may be present.

Thev invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding that sthe invention is not confined to any` strict conformity with the. showing of the drawings, but may be changed and modified so long as such changes and modilications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 isa side elevation of a headlight embodying the invention.

Aconcerne reflector to condense v i Fig. 2 is a. front elevation'as seen from the left hand end of the showing of Fig. 1.

Fig. 3 is Casco-tion Fig. 2.

Fig. 1.

Fig. 5 is a section on the line oof Fig. 4 is a. seetionon the line 4.--4 of 1' on the .line Zit-Soi -eferring to the drawings, there is shown a casing A composed of a cylindrical meinber 1 and in alineinent with a conical projec" tion 2 united by a coupling section 3 held together in telesooping relationby screws L1 or otherwise. l

The conical` section 2 of the casing terminates in a plane end Shaving-a cut-out 6 of" semi-circular contour 'and coveredby'a 'similarly shaped pane 7 of glass,- preferably -l plate glass because of its reet transparency. That end'- of thecylindrical'y portion 1 of the casing A remote from the conical portion 2 is rounded as shown at 8 to accommo date parts to be described.

Secured to the end 8 of the member 1 is a bracket 9 constitntinv a support for a terior of the cylindrical member 1. The brackets 9 and 11 secured tothe interiorv in tile shape of a bowl, further supported by other brackets 11 riveted oz-otherwise madeast to the in-.

Walls o' the casing section 'l constitute a `rigid support therefor and the reilector 10,

is provideg with a. central neck12 extending through to the exterior thereof and shaped to constitute a holder or support for receiving and carrying the basic 'end l. of e lamp socket toV receive an incandescent electriclamp le of the battery type, which lamp is carried at the focal point of the reflector- 10 whereby rays. of light are projected by the reflector 10 in parallel or somewhat con# vergent relatioiriA 4 Located Within the casing member 1 ,is a mirror 15 carried by a support l'made Afast to the inner wall of the Casin 1 -above'the mouth of' the reflector'l'an heidi/.thereto by an adjusting screw 17 associated-with the .Y

said screw" so that ring 18,surrounding` l yusted as `des1red to..

S t e mirrormay be a le side of the casing member 1 vary. the beam oit light directed by the mirror `from the lamp 14 through the win. dow' 7. The mirror lois further supported by bolts 19 serving as pivot bolts.

When the parte described are installed ing plate carried by above the. reflecting elementliaving its opbracket at the igear thereof for lamp 14, is converted into parallel oi* some- What convergent rays, and these rays are directed through the contracted Window 7 to the exterior thereof and in a direction to strike upon the roadway Within moderate distance from the headlight thus preventing any direct rays of light from the lamp 14 from rising high enough' to cause a glare in the eyes of the observer ivho may be located in front of the automobile. This, by avoiding direct line of vision to the headlight lamp 14, effectively revents any glare fiom reaching the eyes of the observer and the blinding effects of the headlight is thereby avoided. The screw 17 is accessible from the exterior ,of the headlight and hence the tilt of the reliector l5 adjustable at the Will of the operator to avoid any glare occurring.

What is claimed ist* l. In a light projecting apparatus, a cylindrical casing having a closed rear end, a truste-conical casing aligning with and seri-urcd'atits rear end to the open end of the said other casing and provided with a removable lsemi-circular light emitting`v means at the front end thereof, a vertically positioned concave reflecting element iii-- ranged within and supported by the lower part of' saidcylindrical casing, a vertically disposed lamp mourned ivitliin and centrally of said reflecting element, a horizontally disposed support carrying an upsfanding attachment with said closed rear end, said support surrounding said reflecting element at its upper edge, opposit'ely disposed brackets carried by the cylindrical casing near its front edge for further securing said support, asupportthe cylindrical casing posite edges downturned to provide attaching flanges. said flanges having apertures for the passage of supporting bolts, and a mirror retained by said supporting plate' rays through the said light emitting means. i

In a light projecting apparatus, a cylindrical casing having a closed rear end,

and further having an aperture through the lower part thereof',l a truste-conical casing aligning with and secured at its rear end. to

the open end of the saidother casing and provided With a removable semi-circular lighT emitting means at the front end thereof, a. vertically positioned conca-ve reflecting element arranged within said cylindrical casing and having a tube like member formed centrally thereof and passing down- Wardly through the aperture in the lower side of said casing, a vertically disposed lamp mounted within and centrally of said reflecting element, a horizontally disposed support carrying an upstanding bracket at the rear thereof forl attachment with the saidclosed rear end, said support surround-v ing said reflecting element at its upper edge and further being of the same contour as the cylindrical casing, oppositely disposed brackets carried b v the cylindrical casing'- near its out-cr dge for further securing 'said support, a pivoted supporting plate carried bv the cylindrical casing above the vreflecting cement, a bracket .attached to the back of said plate and extending forwardly' from the lop edge thereof, an adjusting means extending through and downwardly from 'the top of the cylindrical casing and contacting with said bracket for of said plate, and a mirrorretained by said supporting plate at an inclination with respect. to the reflecting means for projectingy the light rays through the said light emitting means.

In testimony whereof, ive afix our signa.
